Abstract

An expandable stent is provided, wherein the stent is advantageously formed of at least one amorphous metal alloy and a biocompatible material. The stent is formed from flat metal in a helical strip which is wound to form a tubular structure. The tubular structure is not welded but rather is wrapped or coated with a biocompatible material in order to maintain the amorphous metal in its tubular configuration. Said stent can be balloon expanded or self expanding.
